To all fw hom it may concern:

Be it known that I, CHARLIE C. SHET- TERLY, a citizen of the UnitedStates, residing at Franklin, in the county of Johnson and State ofIndiana, have invented a new and useful Improvement lin Locks forAutomobiles, of which the following is a specification.

The object of my invention is to provide a novel and effective deviceadapted to be operated from the dashboard of an automobile to controlthe fuel supply. andshut the same off entirely so as to lock the caragainst unauthorized use; and it is my object to provide a comparativelysimple device adapted to operate with accuracy and positiveness toperform the required operation. I attain these and otherobjects of myinvention bythe mechanism illustrated in the accompanying drawings, inwhich Figure 1 is a view of the device in elevation applied-to theappropriate part of an automobile;

Fig. 2 is a detailed sectional view of the dashboard and the parts ofthe lock connected therewith;

Fig. 3 is a longitudinal sectional view of the locking valve andadjacent parts;

Fig. 4 is a side elevation of a modified form of the lock independent ofthe dashboard mechanism; and

Fig. 5 is a longitudinal section of the device shown in Fig. 4, withparts in elevation.

Like numerals designate like parts throughout the several views.

Referring to the accompanying drawings, Figs. 1-3 represent thepreferred form of my invention constructed for operation from thedashboard of an4 automobile. Mounted in the dashboard is a suitable lock4 and key 5 (a Yale lock preferably being employed). The lock shankorbolt 24 en gages in a driving sleeve 23 which is mounted in a suitableand preferably metallic tube 22 which extends into my lock casing 25.Driving sleeve 23 is composed of a series of links, making it a flexibleoperating member. The lower end of member 23 is attached to a suitableL=shaped plunger 6 which is operatively in contact with a pivotallymountecL pressure plate 7, which in turn is in operative Contact with asuitable bell-crank lever11, one arm of which contacts with the apex(when in closed position) of the'novel double conical valve 13 whichseats in the fuel passage 1 at its point of communication with channel 2Vwhich is connected with the carbureter in some suitable manner. Asuitable channel 3 is in communication with the gas tank.

Mounted within channel 2 I provide ar suitable channel nut 17 whichprovides a stop for spring ,16, which presses against the stem of thedouble conical valve 13 to press the same normally away from its seat 14toward bell-crank lever 11, which latter member is swingable on thepivot 12 and has its upper arm engaging diaphragm 10 and bearing againstpressure plate 7 which is pivoted on thepivot 8 mounted in the threadedring 9 of the casing member 20. I provide a suitablejoint 18 in threadeden- -gagement with member 20, and having its end 19 secured thereto in asultable manner,

as by` rivet 21.V I may and do further pro* videV a suitable lock 26, asshown in Fig. 3, for the purpose of locking the hinged casing or housing25 so that the mechanism of the carbureter locking valve will beinaccessible to anyone except the owner of the Referring to Fig. 1 thereis shown in elevation the tube 22 which extends into the lock housing 25which is shown in its preferred kposition relative to carbureter C andmanifold M.

The operation of key 5 manually in lock 4 swings the L-shaped arm 6 inthe arc of a circle, so as to bring it into or out of operativeengagement with the pivotally mounted pressure plate 7, which in turndepresses or releases the bell-crank lever 11, which latter member inturn presses and seats. or releases and opens the double conical lockingvalve 13, which is positioned to control the supply of fuel and which isnormally pressed against the contacting arm of bell-crank 11, by thetension spring 16.

In the form of the invention shown in Figs. 4 and 5 the tube 22 andflexible sleeve 23 leading to the dashboard, are omitted and lock 4 ismounted immediately in joint Specication of Letters Patent.Patentedlweb. 22, 1921. i i

ferred where the standpoint of convenience isvthe main Aconsiderationand it is desired to obviate raising of the hood to lock the car.

WhatI claim is:

' l. In a lock for automobiles adapted to control the fuel supply, thecombination of a lock and key, means in operative connection with thelock, a pivotally mounted arm actuated by said means, a diaphragmadjacent said arm, a bell crank lever onthe other side of the diaphragmand positioned to be actuated by the above described arm,

a conical valve in operative engagement` vnectiiig said valve casingWith pipes leading to the carbureter and the fuel supply.

2. In a lock for automobiles adapted tol control the fuel supply, theVcombination of a lock and key mounted on the dashboard of theautomobile, a flexible operating member connected to and operated by theaforesaidV lock, an arm actuated by the flexible operating member, asecond arm actuated by the first named arm, said second arm being inengagement with the outer surface of a diaphragm, said diaphragmoperating to'prevent escape of thefuel, a valve actuating memberengaging the inner surface:

Y of the diaphragm and positioned to be actuated by the arm whichengages the diaphragm on its outer surface, a valve in the path of thefuel, a valve casing, and means for connecting the valve casing tothepipes leading to the carbur-eter and the fuel sup. ply. ,Y 1 n Incombination With the mechanism de# adapted to completely inclose thevalve casing and valve actuating parts in proximity to the valve, and akey-operated lock mounted in said metal housing and arranged to locksaid housing, whereby .toV prevent unauthorized persons from gettingaccess to the valve easing Without first breaking they -inetal housing.

4. In a lock Vfor automobiles adapted to control the fuel supply, thecombination of a lock and key mounted on the dashboard of theautomobile, a flexible operating member connectedJ to and operated bythe afore-Y Vand valve actuating parts are mounted, and

means for connecting said valve casing with pipes leading to thecarbureter and the fuel supply. Y Y e CHARLIE C. SHETTERLY.
